GLOBE 0a SHADE HOLDER Filed May 29, 1929 4 won/7,1 a: N/COLA CPITR/LLQ 91-7-0 e/van Patented Apr. 22, 1930 eLoBn on SHADE Herman Application filed. May as,

, The object of my device is to make a globe or shade holder to be used particularly for globes or shades for street lamps. A further 7 object is to makea globe or shade holder that will holdthe shade or globe positively and prevent the breakage of the globe on account of vibration. These globes are positioned on poles and where the poles are located on viaducts or bridges or even'on cityv streets, they are subjected to varying amounts of vibration or movement. This vibration or movement fractures the globe when the ordinary globe holder is used. My device prevents the breakage from such vibration and also prevents breakage incident to the removal and positioning on the holder of the globe. It is necessary to be able'to remove the globe at intervals from the base or support for the purpose of cleaning the globe '20 and replacing burnt out lights. By the use of my device the globe may be easily removed and replaced without disturbing the portion of my device that comes in contact with the globe. By the use of my device'the strains are equalized and minimized between the metal portion of the holder and the globe. When the conventional method is employed, that is when screws come in contact with. the globe, strains are set up in the glass adjacent the screws, which eventually crack the glass. .My globe holder may be made of few and simple parts and lends itselfreadily to multi-- ple production.

With these and other objectsin view my invention has relation to certain novel features of construction and arrangement of part-s as will be hereinafter more fully described, pointed out in the claim and illustrated in the rdrawings, in which Fig. 1 is a frontelevation of my device, showing aportion of the globe. Fig. 2 is a plan view of my device. Fig. 3 is a',transverse median section of Fig. 2. g

cured tothe top of the pole by meansof the annular depending flange 7. Numeral 8 designates the outer wall of the base 6 andv numeral9 designates an inner annular flange;

Between the outer wall Sand the inner an- *nula'r 'flange9 isformed the annular recess 10. The outer wall 8 is considerably higher than the inner annular flange 9. In the outer wall 8 are formed the tapped radial holes 11 into which are secured in threaded engagement the screws 12. Numeral '13 designatesthe globe having-the annular flange 14 formed at itslower end. Numeral 15 designates a gasket, which conforms to the shape of the annular'flange 14 andis of the same circum- 1 ference as the annular flange 14:. and is placed in contact with the annular flange 1 1. Nu-

meral16 designates a. split ring, whichis split into two equal arcs. At the free ends are: formed the ears 17 having the tapped holes 18 passing therethrough. Numerals 191 desig- I nate screws passing through the tapped holes 18 of the ears 17. Numerals 20 designates coiled springs positioned over thescrews 19 between the head and the nearest of the ears 17 The split ring 16 is placed over the gas-. ket15 and the screws 19 tightened against the compression of the coiled springs 20. On

"the split ring 16 are formed the lugs 21,

which extend radially outward and downward from the body of the split ring 16. The split ring is shown in its inverted position in Fig. 4. Numerals 22 indicate slots formed in the lugs 21. There are four such lugs 21 shown in Fig. 2. In assembling after the split ring 16 has been secured as shown in Fig. '3 to the globe 13, the split ring is placed on the base 6, so that the lugs 21 extend downthe globes are mounted is vibrated, a slight wardly in sliding engagement on the outer wall 8. The screws 12 are so positioned that vibration of the globe is permitted within the split ring 16 against the compression of the coiled springs 20. This movement is ex tremely slight, but is suflicient to prevent the breaking or fracture of the globe.

What I claim and mean to secure by Letters Patent is:

A base having an outer wall, screws in threaded engagement in said outer wall, a

I split ring positione'don said base, said split ring having lugs formed thereon with slots formed therein for engagement with said 7 screws said split ring being composed of se' ments' having ears at their free ends with threaded holes passing therethrough, screws 'inthreaded engagement in the holes-in the lugs formedon said split ring, a coiled spring" securedfonsa-id screws betweenthe head and the adjacent ears of said split ring, aglobe, a'gasket secured-to said g10be,said gasket in frictional engagement With Said split ring.

Intestimony whereof I affix my signature. NIOOLAGESARE PETRILLQ.
